Hyderabad: STMicroelectronics, suppliers of system-on-chip (SoC) products for the wireless market, has announced a turnkey solution for 802.16e base-station modems. Based on the market's first SoC baseband processor for wireless infrastructure applications (STW51000), ST's WiMAX offering provides levels of silicon integration with optimised software libraries, opening a path to next-generation mobile broadband services, says STMicroelectronics in a press release.
WiMAX / IEEE 802.16, which provides worldwide interoperability for microwave access, is a global standard-based technology for broadband wireless access. The company says the new 'mobile' 802.16e standard ushers in a seamless, nomadic phase of WiMAX, where base stations can communicate with moving devices, allowing users to move around and maintain their broadband connection. Industry analysts expect WiMAX subscribers to exceed 50 million by 2010, with worldwide sales of WiMAX equipment growing at a CAGR of 140 per cent over the next five years.
"ST has expanded its offering of turnkey system solutions for wireless base stations with the implementation of mobile WiMAX," said Philippe Geyres, executive VP, home, personal and communications, STMicroelectronics. ST's baseband modem combines two quad-MAC DSP cores, each running at 600MHz, with a 300MHz ARM926 RISC core, 16 Mbit of embedded SRAM memory, and dedicated channel decoding co-processor in a single device, demonstrating the industry's lowest cost-per-channel and highest throughput. 802.16e benchmarks have shown that a single STW51000 can address a complete 10MHz TDD (time-division-duplexing) PHY running on the DSPs, as well as the lower part of the MAC running on the ARM926.
